GENERAL SAFETY INFORMATION
Intended Use
The 3M™ Macurco™ GD-6 Combustible Gas Detector, Controller and Transducer is a low voltage device with selectable 4-20mA
output, buzzer and digital display options. It is an electronic detection system used to measure the concentration of combustible
gas and provide feedback and automatic exhaust fan control to help reduce combustible gas concentrations in parking garages,
maintenance facilities or other light commercial applications. The 3M™ Macurco™ GD-6 Combustible Gas Detector is a low level
meter capable of displaying from 0-50% LEL (Lower Explosive Limit) of combustible gas. The 3M™ Macurco™ GD-6 Combustible
Gas Detector is factory calibrated and tested for proper operation, but can also be calibrated in the field.

Use For
The 3M™ Macurco™ GD-6 Combustible Gas Detector helps combustible gas detection and automatic exhaust fan control
for automotive maintenance facilities, enclosed parking garages, warehouses with forklifts, etc. The 3M™ Macurco™ GD-6
Combustible Gas Detector can be used with 12VDC or 24VDC N.O. (fire/security) panels.
Use only for monitoring the gas which the sensor and instrument are designed to monitor. Failure to do so may result in
exposures to gases not detectable and cause sickness or death. For proper use, see supervisor or User Instructions, or
call 3M in U.S.A., 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.

General Description
The 3M™ Macurco™ GD-6 Combustible Gas Detector is a low voltage, dual relay combustible gas (EX) detector and automatic
ventilation controller. The 3M™ Macurco™ GD-6 Combustible Gas Detector uses a microcomputer controlled, electronic
system to measure the concentration of combustible gas, actuate relays and provide a 4-20mA (0-50% LEL) output. The
3M™ Macurco™ GD-6 Combustible Gas Detector is low maintenance with a long life (5+ years) pellistor sensor and optional
gas test and calibration kits. The 3M™ Macurco™ GD-6 Combustible Gas Detector is a low level meter capable of displaying
from 0-50% LEL of combustible gas.
